AO2 Memory

AO2 Memory is a shared memory layer for AI tools, reusing context across agents via MCP, API key, SDK, or CLI.

Overview

AO2 Memory is a shared memory layer for AI tools. The product is positioned as a way to avoid re-explaining the same project context every time you switch between agents, so one tool can write memory that another can read later.

The site describes AO2 as an MCP server you connect to tools such as Claude, ChatGPT, Codex, OpenClaw, Hermes, Manus, or your own apps through an API. It emphasizes structured memory that you control and can export, rather than a hidden store locked inside a single assistant.

Features

Multiple connection methods

Connect AO2 through MCP, API key, SDK, or CLI so different AI tools and apps can read and write to the same memory layer.

Shared memory across tools

Use the same memory across Claude, ChatGPT, Codex, OpenClaw, Hermes, Manus, and custom apps connected by API.

Activity history and rollback

See changes made by agents, review activity, and roll back earlier updates when needed.

Fine-grained access control

Scope access to specific records or fields, and issue temporary keys that expire automatically.

Structured records

Store information as structured records instead of an unsearchable text blob, using fields such as title, status, due date, priority, and number.

Portable export

Export memory with one command and move it out as Git, JSON, Markdown, or CSV.

Use Cases

Cross-tool context sharing
Keep project context in one place so switching from one AI assistant to another does not require repeating the same background information.
Reviewing and rolling back agent changes
Track agent edits over time, inspect what changed, and undo updates when an AI writes something you do not want to keep.
Structured note and project storage
Store notes and project data as records with fields instead of dumping them into plain text, making the memory easier to reuse later.
Embedding memory in custom apps
Connect custom apps or internal workflows through the API when you want AI memory available outside a single chat interface.
Portable export and backup
Export memory to Git or common file formats when you want to keep ownership of your context outside the product.

Pros and Cons

Works with several connection methods, including MCP, API key, SDK, and CLI.
Supports structured records instead of only free-form notes.
Includes activity visibility and rollback for agent-made changes.
Allows export to Git, JSON, Markdown, or CSV so memory is portable.

Cons

The pricing page was not accessible in the collected sources, so detailed plan terms and exact limits are not fully verifiable from the available evidence.
The site provides limited documentation in the collected material, so deeper setup, team, and workflow details are not fully explained here.
